One if the most common things that happens when transporting a computer system is connections getting knocked loose. Hopefully, this is what has occurred rather than more permanent damage from the move.
WARNING: It is best to have an experienced technician perform the following procedures.
That being said.... if you feel comfortable digging around inside your system or have someone else who is... here's what you need to do.
Shut down your system.
Open up the computer case.
Make sure you are grounded and the computer is completely disconnected from any power source. Touching a metal part of the case prior to touching anything inside the case is always a good idea.
Re-seat any accessory cards present (ie. video card, sound card, modem, etc.). 'Re-seating' means carefully removing them and then carefully and firmly inserting them back into their respective slots on the motherboard.
After that, check all ribbon and cord connections to the drives (ie. Hard Drives, CDROM Drives, Floppy Drive, etc.).
In particular, based on your comments, pay close attention to the floppy drive connections.
Next, make sure all power connections are secure. That is, check the connections from the power supply within the case to where they plug into drives, cards or to the motherboard.
Then re-seat all RAM sticks (be very careful doing this as even a slight static charge can damage RAM).
While you have the case open, it would be a good idea to blow out any lint or dust bunnies. Do this using one of the many compressed gas duster/sprayers available at any office supply store (be sure NOT to shake the can before use). Although it is doubtful that dust is the cause of your issue, it's a good idea to clean it out periodically... primarily so the system can be cooled by its fans optimally.
Once you are SURE that all cards are seated properly, all drives are solidly connected, all power connections are secure, RAM has been re-seated, dust has been removed from the fans and board, then close the case, make sure all connections are correct at the back of the system, connect to power and restart your computer.
Please let me know once this has been completed and what the outcome is.
